BACKGROUND Indirect muscle injuries (IMIs) are a considerable burden to elite football (soccer) teams and prevention of these injuries offers many benefits. Preseason medical, musculoskeletal and performance screening (termed periodic health examination (PHE)) is used to help determine players at risk of injuries such as IMIs, where identification of PHE-derived prognostic factors (PF) may inform IMI prevention strategies. Furthermore, using several PFs in combination within a multivariable prognostic model may allow individualised IMI risk estimation and specific targeting of prevention strategies, based upon an individual's PF profile. No such models have been developed in elite football and the current IMI prognostic factor evidence is limited. This study aims to: 1) to develop and internally validate a prognostic model for individualised IMI risk prediction during a season in elite footballers, using the extent of the prognostic evidence and clinical reasoning; 2) explore potential PHE-derived PFs associated with IMI outcomes in elite footballers, using available PHE data from a professional team.
METHODS A retrospective review has been completed of PHE and injury data, routinely collected over 5 years (from 1st July 2013 to 19th May 2018) from a population of elite male players at an English Premier League football club. Of 60 candidate PFs, 15 were excluded. Ten factors will be included in model development, identified from a systematic review, missing data assessment, measurement reliability evaluation and clinical reasoning. A full multivariable logistic regression model will be fitted, to ensure adjustment before backward elimination. The performance and internal validation of the model will be assessed. The remaining 35 candidate PFs are eligible for further exploration, using univariable logistic regression to obtain unadjusted risk estimates. Exploratory PFs will be grouped according to type and incorporated into multivariable logistic regression models to determine risk estimates.
DISCUSSION This study will offer insights into clinical usefulness of a model to predict IMI risk in elite football and highlight the practicalities of model development in this setting. Exploration may identify other relevant PFs for future confirmatory studies, model updating, or influence future injury prevention research.

Other: Preseason Periodic Health Examination Completion
all available players completed a mandatory PHE on one of three days during the first week of the season. Typically, the musculoskeletal and performance components of the PHE included: 1) anthropometric measurements; 2) medical history (i.e. previous injury history); 3) musculoskeletal examination tests; 4) functional movement and balance tests; 5) strength and power tests.
- Number of participants with an indirect muscle injury. [ Time Frame: 11 Months (1 football season) ]Indirect muscle injury defined according to Terminology and Classification of Muscle Injuries Consensus Statement
- Number of participants with an indirect muscle injury affecting the hamstring muscle group. [ Time Frame: 11 Months (1 football season) ]If there is a sufficient number of outcomes, indirect muscle injuries (defined according to the Terminology and Classification of Muscle Injuries Consensus Statement) that affect the hamstring muscle group may be subgrouped and analysed accordingly.
- Number of participants with an indirect structural muscle injury. [ Time Frame: 11 Months (1 football season) ]If there is a sufficient number of outcomes, indirect muscle injuries will be categorised into structural injuries (defined as type 3 or 4 injury using the Terminology and Classification of Muscle Injuries Consensus Statement) and analysed accordingly.
- Number of participants with an indirect functional muscle injury. [ Time Frame: 11 Months (1 football season) ]If sufficient there is a sufficient number of outcomes, indirect muscle injuries will be categorised into functional injuries (defined as type 1a to 2b injuries using the Terminology and Classification of Muscle Injuries Consensus Statement) and analysed accordingly.
